Effect of Buoyancy on the Radiative Extinction Limit of Low-Strain-Rate Nonpremixed Methane-Air Flames

October 1, 2007

Author(s)

Anthony P. Hamins, Matthew F. Bundy, C B. Oh, Sung C. Kim

The structure and extinction of nonpremixed flames were investigated through comparison of experiments and calculations using a counterflow configuration. Experiments were conducted at the NASA Glenn Research Center's 2.2-s drop tower to attain suppression

Analysis of Thermocouple Behavior in Compartment Fires

September 27, 2007

Author(s)

Sung C. Kim, Anthony P. Hamins, Matthew F. Bundy, Gwon Ko, Erik L. Johnsson

The present study uses numerical simulations and analytical solutions to investigate the heat transfer processes associated with bare bead and double shield aspirated thermocouples. The uncertainty of thermocouple temperature measurements is emphasized

Measurements of Heat and Combustion Products in Reduced-Scale Ventilation-Limited Compartment Fires

July 10, 2007

Author(s)

Matthew F. Bundy, Anthony P. Hamins, Erik L. Johnsson, Sung C. Kim, Gwon Ko, David B. Lenhert

The present study investigated the flow and heat transfer characteristics of aspirated thermocouples using a simple energy balance model and a 3D CFD model. The calculations quantify the systematic measurement error, providing an estimate of the

Measurements of Heat and Combustion Products in Reduced-Scale Ventilation-Limited Compartment Fires

July 1, 2007

Author(s)

Matthew F. Bundy, Anthony P. Hamins, Erik L. Johnsson, Sung C. Kim, Gwon Ko, David B. Lenhert

A series of new reduced-scale compartment fire experiments were conducted, which included local measurements of temperature and species composition. The measurements are unique to the compartment fire literature. By design, the experiments provided a
